-"""Fixer that cleans up a tuple argument to isinstance after the tokens
-in it were fixed. This is mainly used to remove double occurrences of
-tokens as a leftover of the long -> int / unicode -> str conversion.
-
-eg. isinstance(x, (int, long)) -> isinstance(x, (int, int))
- -> isinstance(x, int)
